The steady increase in global temperatures, resulting from the combustion of fossil fuels and the accumulation of greenhouse gases (GHG), continues to destabilize all ecosystems worldwide. Although annual emissions must halve by 2030 and reach net-zero by 2050 to limit some of the most catastrophic impacts associated with a warming planet, the world's efforts to curb GHG emissions fall short of the commitments made in the 2015 Paris Agreement (1). To this effect, July 2021 was recently declared the hottest month ever recorded in 142 years (2). The ramifications of these changes on global temperatures are complex and further promote outdoor air pollution, pollen exposure, and extreme weather events. Besides worsening respiratory health, air pollution, promotes atopy and susceptibility to infections. The GHG effects on pollen affect the frequency and severity of asthma and allergic rhinitis. Changes in temperature, air pollution, and extreme weather events exert adverse multisystemic health effects and disproportionally affect disadvantaged and vulnerable populations. This article is an update for allergists and immunologists about the health impacts of climate change, already evident in our daily practices. It is also a call to action and advocacy, including integrating climate change-related mitigation, education, and adaptation measures to protect our patients and avert further injury to our planet.
To test whether lumbar Erector Spinae Plane Block (ESPB) provides superior analgesia compared to placebo in patients undergoing Percutaneous Nephrolithotomy (PCNL), using reduction in postoperative opioid consumption, delay in rescue analgesia demand and reduction of pain scores as outcome measures.
34 adult (18-60 years) ASA I and II patients undergoing unilateral PCNL were randomized into two groups (Bupivacaine and Saline) - both receiving ipsilateral ESPB at L1 vertebral level with either 20 ml 0.25% Inj. Bupivacaine or 30 ml normal saline respectively, at the start of the surgery under general anaesthesia. The primary outcome measure was total 24-hour rescue opioid analgesic requirement, while time to first demand of rescue analgesic and pain scores at 2, 12 and 24 hours postoperatively were secondary outcomes.
The 24-hour requirement of rescue analgesic Tramadol was significantly lower (53.5 ± 29.6 vs 121.2 ± 51.1 mg) [mean ± SD] (p = 0.001) and time to first demand of rescue analgesia was more (14.1 ± 8.4 vs 6.0 ± 5.6 hours) [mean ± SD] (p = 0.001) in the Bupivacaine group as compared to placebo. The pain scores were significantly lower in the Bupivacaine group at 12-hour post-operatively [4 (3,4) vs 5.5 (5,6)] [median (IQR)] (p = 0.001), while the stone-load, surgical duration and intraoperative opioid use were comparable between the two groups and no block-related complications were noted in any patient.
Post-PCNL, ipsilateral lumbar ESPB reduced 24-hour opioid consumption and delayed time to demand for rescue analgesia as compared to placebo.

To assess the utility of genomic testing in risk-stratifying Black patients with low and intermediate risk prostate cancer.
We retrospectively identified 63 Black men deemed eligible for active surveillance based on National Comprehensive Cancer Network® (NCCN) guidelines, who underwent OncotypeDx® Genomic Prostate Score™ testing between April 2016 and July 2020. Nonparametric statistical testing was used to compare relevant features between patients reclassified to a higher NCCN risk after genomic testing and those who were not reclassified.
The median age was 66 years and median pre-biopsy PSA was 7.3. Initial risk classifications were very low risk seven(11.1%), low risk 24(38.1%), favorable intermediate risk 31(49.2%), and unfavorable intermediate risk one(1.6%). Overall, NCCN risk classifications after Genomic Prostate Score testing were significantly higher than initial classifications (p=0.003, Wilcoxon signed-rank). selleck chemicals llc Among patients with discordant risk designations, 28(28/40, 70%) were reclassifiests may better inform treatment decisions on an individualized basis.
To determine whether 24-hour urine testing in Veterans with USD (urinary stone disease) reduces or delays urinary stone recurrence.
Cohort study of national health record data from Veterans Health Administration from 2007 through 2013. We utilized a study population of 130,129 Veterans with USD based on diagnostic or procedural codes and excluded those with USD claims in the two years before cohort entry. We then created a propensity-score matched cohort of 14,854 Veterans based on completion of 24-hour urine testing within 6 months of stone diagnosis. Primary outcome was time-to-next clinically significant stone event, defined as an emergency department visit, inpatient admission related to a urinary stone, or urologic stone procedure with 5-year follow up.
Of 14,854 Veterans in the propensity-score matched cohort, 8,560 (57.6%) experienced a recurrent USD event. Completion of 24-hour urine testing was associated with a higher risk of developing a second stone event (hazard ratio (HR) 1.17, 95% confidence interval (95% CI) 1.12-1.22). Among Veterans with known recurrent disease, we examined time to a third stone event. In this cohort of 4,736 patients, completion of 24-hour urine testing was not associated with a higher risk of developing a third stone event (HR 1.06, 95% CI 0.99-1.12).
Completion of 24-hour urine testing was not associated with a reduction in urinary stone recurrence. These findings challenge the validity of a longstanding recommendation in general medicine, nephrology, and urology practice.

To provide a scoping review of the economic burden of non-cancerous genitourinary conditions (NCGUCs).
A scoping review of the literature surrounding the economic costs associated with NCGUCs was conducted for literature published between 1990-2020. The articles were screened and relevant articles were selected for review. These articles were abstracted with information pertaining to the costs surrounding NCGUCs. A descriptive analysis of the data was conducted.
We found 3298 articles in our scoping review. Of these, we found 38 relevant articles related to pelvic floor dysfunction and pelvic organ prolapse, interstitial cystitis, neurogenic bladder, nocturia, urinary tract infections, urolithiasis, urinary incontinence, benign prostatic hyperplasia, overactive bladder, and erectile dysfunction of which the data is reviewed.
Although the data in estimating the economic burden is limited, existing evidence demonstrates a significant component of health care spending on NCGUCs. Much of the spending is out-of-pocket and indirect costs that are difficult to measure which may increase the magnitude of the costs. There is a need for future research that takes a holistic look at the economic impact of NCGUCs.

To detect seed-based functional connectivity (FC) between various cortical sub-regions and the thalamus in lifelong premature ejaculation (LPE) patients and explore whether specific thalamocortical networks are significantly altered in PE patients compared to healthy controls (HCs) Methods Fifty non-medicated LPE patients and 40 age-matched HCs underwent a resting-state functional MRI. FC was adopted to identify specific thalamocortical connectivity between the thalamus and six cortical regions of interest (i.e. the motor cortex/supplementary motor, the prefrontal cortex, the temporal lobe, the posterior parietal cortex, the somatosensory cortex and the occipital lobe). In LPE patients, regression analysis was subsequently conducted to assess relationships of thalamocortical connectivity with the Premature Ejaculation Diagnostic Tool (PEDT) score and the Intravaginal Ejaculatory Latency Time (IELT).
LPE patients had significantly decreased FC between the motor cortex and bilateral ventral thalamus, between the prefrontal cortex and left dorsomedial thalamus, as well as between the temporal cortex and bilateral ventromedial thalamus. In LPE patients, PEDT score was significantly positively associated with the thalamus-posterior parietal cortex FC, and negatively associated with the thalamus-temporal cortex FC, while IELT was positively associated with the thalamus-temporal cortex and thalamus-motor cortex FC.
These results enrich the imaging evidence for the understanding of the neurobiological mechanisms and/or consequences of LPE.

Carbon dots (CDs) were synthesized by hydrothermal method with citric acid and ethylenediamine as carbon sources. Then, CDs (5 ml, 5 mg‧L-1) were sprayed on 25th day-old maize (Zea mays L., drought-stress, 35% soil moisture) for seven consecutive days (spraying ultra-pure water as control), after which the physiological parameters and rhizospheric properties of maize under drought were evaluated. Foliar sprayed CDs (5 mg‧L-1) could increase root exudates (e.g., succinic acid (14.5 folds), pyruvic acid (10.0 folds), and betaine (11.8 folds)), and modify microbial community. Particularly, the relative abundance of Pseudomonas, Sphingomonas, Nitrospira, and Conocybe were significantly increased by 344.4%, 233.3%, 126.2%, and 122.6%, respectively. The altered microbial abundance could improve soil available nitrogen and phosphorus by 33.5% and 16.8%, respectively, and increase plant water uptake by 37.2%. The change of exudate synthesis and microbial abundance could be driven by the significantly increased in net photosynthesis rate by 122.9%, and carbohydrate content by 35.4% in shoots and 113.6% in roots, respectively upon foliar application of CDs. Meanwhile, fresh weight of shoots and roots were increased by 62.1% and 50.6%, and dry weight of shoots and roots were increased by 29.2% and 37.5%, respectively. These results demonstrated that foliar application of CDs could improve the rhizosphere environment to enhance maize drought tolerance and even growth. Therefore, foliar application of CDs would be a promising strategy for sustainable nano-agriculture in response to drought stress.The successful use of visible and near-infrared (Vis-NIR) reflectance spectroscopy analysis requires selecting an optimal procedure of data acquisition and an accurate modeling approach. In this study, Vis-NIR with 350-2500 nm wavelengths were applied to detect different forms of lead (Pb) through the spectrally active soil constituents combining principal component regression (PCR) and Partial least-square regression (PLSR) for the Vis-NIR model calibration. Three clouds with different soil spectral properties were divided by the Linear discriminant analysis (LDA) in categories of Pb contamination risks "low," "health," "ecological," ranging from 200 to 750 mg kg-1. Farm soils were used for calibration (n = 26), and more polluted garden soils (n = 36) from New York City were used for validation. Total and bioaccessible Pb concentrations were examined with PLSR models and compared with Support Vector Machine (SVM) Regression and Boosting Regression Tree (BRT) models. Performances of all models' predictions were qualitatively evaluated by the Root Mean Square Error (RMSE), Residual Prediction Deviation (RPD), and coefficient of determination (R2).
